Status: published. Published: 2026-11-05. Updated: 2026-11-12.

Joomla Extension - jreviews.com - Secret configs cached in a web-accessible in JReviews 1.0.0-5.12.0, 6.0.0-6.6.9 - JReviews caches its full settings table, including the Joomla global configuration secret (copied into cms_secret) and third-party API keys and secrets, to a serialized file under components/com_s2framework/tmp/cache/core/ inside the web root. The file has no PHP guard and the directory has no .htaccess, so anyone who knows the file name can read it without authentication.
